We're dividing 77534916 by 129 
We want to divide 77534916 by 129.

Moving on to step 1:
129 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 129

Going ahead to step 2:
If we divide 77 by 129, we get 0 and a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 129

Going ahead to step 3:
129 goes into 775 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 774 away from 775, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 129

Step 4:
13 divided by 129 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 13 to get 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 129

On to step 5:
When dividing 134 by 129, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 601.0
Subtract 129 from 134 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 129

Advancing to step 6:
129 can be fit into 59 0 times, resulting in a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 6010.0
If we subtract 0 from 59, we get 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 129

Advancing to step 7:
591 divided by 129 is 4 with a remainder of 75.
Use 4 as the next digit of our solution. 
Result so far: 60104.0
Subtracting 516 from 591 leaves us with 75.
Include the next digit (6) from the dividend after 75, then repeat: 756 / 129

Going ahead to step 8:
129 goes into 756 5 times with a remainder of 111.
Record the quotient 5 as the next digit in the result. 
Result so far: 601045.0
If we take 645 away from 756, we end up with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Moving on to step 9:
1110 divided by 129 is 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 601045.8
Subtract 1032 from 1110 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 10:
129 goes into 780 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 601045.86
Subtracting 774 from 780 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
129 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 601045.86
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
If we divide 600 by 129, we get 4 and a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 601045.8604
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 13:
If we divide 840 by 129, we get 6 and a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 601045.86046
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 14:
129 goes into 660 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 601045.860465
If we take 645 away from 660, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 15:
129 can be fit into 150 1 times, resulting in a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 601045.8604651
Subtract 129 from 150 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
210 divided by 129 is 1 with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 601045.86046511
The remainder is 81 after subtracting 129 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 601045.86046511 with a remaining 8.1e-08.
